How to choose a video camera for home security

A good video surveillance camera system is the most comprehensive method of securing homes, let's see which are the best on the market

Nowadays security is very important. On the Internet as well as in everyday life. A good system to secure our homes is to equip them with video surveillance cameras. In this way, we can constantly monitor the dangers coming from intruders, even when we are not at home.

There are an almost infinite number of video surveillance cameras that we can use in our homes. They vary in price, features and functions. They range from the cheapest to the very expensive ones. We ourselves can think of setting up a personal video surveillance network using some of today's most common devices such as smartphones, PCs and tablets. There are several reasons to place a surveillance camera: they are, in fact, deterrents against thieves. Especially if the video surveillance system is well signposted. But not only can we reduce damage from fire or flooding. But also monitor people who are elderly or not completely self-sufficient.

Which video surveillance camera to choose

The question at this point is: what is the best video surveillance camera system according to our needs? To answer this question, let's take a look at the main camera offerings currently available in the market. The simplest and most economical video surveillance system is represented by a video camera combined with a PC. It usually uses software that allows you to make live video calls to monitor the situation in the house even in case of our absence. To activate this system, simply connect the cam with a cable, or use a Wi-Fi camera, and obviously leave it on. This system costs very little but has several disadvantages. First, we'll have to leave the computer on all the time, which means a large power consumption, a continuous overload on the PC battery that will soon stop working properly, and also dangerous overheating. Besides, if the power fails, the PC will only guarantee a few hours of autonomy. This system doesn't have notification services, which are very useful for alerting us via SMS in case of danger or attempted intrusion. But it is possible to record video on a hard disk.


To increase the functionality of the security webcam service more computers we can think of using UMTS cams. These are surveillance cameras that always use video calls but are equipped with a SIM card. They are a kind of cell phone for video surveillance. Whenever we want to take a look at our house all we have to do is dial the number. Beware though they are more expensive than the security cameras described above.

IP Camera

IP cameras are those always connected to the Internet. This is a type of camera that generates a video signal in digitized form and in a format ready for direct transmission over a data network, without the need for analog-to-digital conversion, and able to be controlled directly over the data network itself. In practice they are cameras with their own IP that we can access, provided we have a connection, from anywhere in the world. The only flaw in this system is that the IP address provided by the provider is often variable, so each new connection of the IP cam will be assigned a new address. To get around this problem we can use DDNS (Dynamic Domain Name System), so every time we access the URL of our surveillance camera through a web browser we will be redirected directly. There are a few factors to consider when evaluating an IP camera for home surveillance. Usually they need to be plugged in, which means they need to be placed near an outlet. We avoid those that also need an Ethernet cable and prefer those that directly use a Power over Ethernet, meaning that the cable for the power supply is also the same for the connection. Next, we choose an IP cam that is rain and dust resistant. They are more expensive but if you plan to use them outdoors it is the only solution. Beware then of static IP cameras, that is, those that have only one field of view. It is always preferable to buy robotic ones so that they can be moved remotely in case of need. There are also those with a zoom or a 360° Fisheye view. To choose the resolution we must take into account the speed of our ADSL line. The higher the resolution the more we will use the connection. Moreover there are some models with night vision thanks to infrared led. As far as prices are concerned, with about 40 euros we can get a fixed IP cam, while with 70 we'll have a wireless camera of enough quality. As you go up with the price then we will find the most complete models with all the features described above.
